Replacing a roof on a Corsa B?

[Alex.r]

Just wondering how difficult and what sort of work is involved to replace a roof on a Corsa B? Would it affect the structural integrity of the shell etc?

As you can see its looking a bit worse for wear.

Remove the roof rails and windscreen, and take off the boot completely, then its a case of drilling out the spot welds all the way around.

[Alex.r]

Then just weld the new one in? Would you seal it with something?

[ardenvxr]

yes, seal it with body sealant all around the edge and spot weld the new skin in

[Alex.r]

Cool how do think this sort of job should take?

[ardenvxr]

i'm guessing you mean how long, well you need to remove the headlining and pillar trims inside the car, then remove tailgate, sunroof if it has one and front screen, and then drill all the spot welds out, thats a good few hours work in itself

[Alex.r]

Yea I meant how long haha
So all in all a good days work to be done on a nice sunny day then,
Cheers guys!

well the roof needs painting once its fitted so 2-3 days tbh

[Alex.r]

Can you not use another one from a scrapyard or something?

[ardenvxr]

you can but i wouldn't bother

[Joker]

I heard that welding the roof warps it cus of the heat of the welder? how are people getting around that?

[fray]

spot welds

How come?

its spot welded, isn't as much heat in spot welding as there is in mig welding

[ardenvxr]

How come?

because they get pretty fooked when removing them

You mean continual welding i hope lmao You can still spot with mig.

Whats actually wrong with yours? Surely you can just have it painted, would be a damn sight easier.

its more plug welding with a mig though tbh, but yes continual welding will easily warp a roof

You won't really be able to use a second hand one, especially on your first go as they kink and generally wreck them selves.

you can mig a roof on, ideally you want to spot weld it on, but as a diy job mig plugs will be fine, you shouldn't have too much problems with heat distortion as theres ridges and corners where your welding so its not like your welding a flat panel.

Ah I see

It's all dented in, you can't really see on the pic but will get hold of another one an it has rust patches everywhere too. Hoping to sell it on as a shell aswell.

My dads a welder by trade so I'll ask him to do the welding part, so hopefully should be ok.

Here's a better pic of the roof.
